The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions. It provides continuous monitoring of gas and moisture levels to alert users of developing faults and minimize the risk of unplanned outages. The M2-X builds on GE’s strong domain expertise to deliver an optimized, low maintenance monitoring device with an extended sensor life.
Small form factor, no moving parts, low maintenance, and support for APM software analytics, enabling fleet level deployments
Condition monitoring for a wide range of transformers with mineral insulating oils or ester based fluids (natural and synthetic)
Extending beyond DGA monitoring, through the connection of sensors, the Hydran M2-X can monitor other parameters such as top oil temperature, load current and through the use of IEEE based mathematical models, can provide further insight on changing transformer conditions
Providing critical transformer gas behavior data for Asset Performance Management (APM) strategies, facilitating planning of site intervention and maintenance activities
Supports a wide range of communication methods and protocols to enable easy and secure integration with GE's digital platforms including Perception™ transformer fleet management software, DS Agile substation HMI, PREDIX™, and other APM software tools, historians and SCADA systems
Field proven solution, delivering online DGA solutions for over 40 years
Over 50,000 Hydran units sold worldwide
Estimated sensor life in excess of 10 years*
7 year product warranty
Compatible with various transformer oil types (standard mineral insulating oils and newer natural and synthetic ester based fluids)
Available with the traditional Hydran composite gas (H2, CO, C₂H₂, C₂H₄) sensor or with a discrete Hydrogen only (H2) sensor
Easily upgradable in the field to accept analogue signals to monitor other key transformer parameters
Computation of winding hot spot and other IEEE transformer models for enhanced diagnostics of the transformer’s condition (depending on sensors installed)
Integrates with Kelman multi-gas DGA devices
Easy to install on a single existing transformer valve, often without an outage required
Integrated display and keypad for simplified local user interaction and data visualization
Built-in moisture sensor provides water in oil measurement, critical to identifying paper degradation and leaking gaskets
Compatible with GE’s acclaimed Perception™ software to download, trend and analyze transformer health data
Advanced, flexible and expandable DGA monitoring solution tailored for utility and industrial transformers.
Easily integrates with Kelman multi-gas DGA devices and the Multilin 845 protection & control relay to provide continuous synchronization of chemical and electrical measurements for enhanced transformer monitoring.
